Well, submitting bugs and patches is not allowed at all without having a pre-existing gitlab account, there's no apparant way to get a gitlab account, and the mailing list link leads to a 404 page not found, so perhaps bug-reports and patches aren't all that appreciated after all. But maybe you meant submitting bug reports on the page here? I can do that!

This is for SBCL 1.2.10 on Arch Linux, readline library version 6.3

pressing "Up-arrow" introduces garbage binary data to the input, if you are at the beginning of input history. Checking whether you are at the beginning of a list is pretty basic stuff... so this package should probably do that.

I don't know why I was having trouble with end-of-file conditions. It started working for some reason, ctrl-d and it prompts and lets me exit.

Might offer some patches later, but of course I can't send them to common-lisp.net without a gitlab account.
